Abstract
Systems and methods for connecting and disconnecting to a DSL ring are provided. A cross connect node is used to connect multiple endpoints into a DSL ring. When a given endpoint is powered down, a cross connect bypasses that endpoint such that the ring is maintained. POTS service is provided irrespective of whether the endpoint is bypassed for the purpose of the ring. The status of a bypassed node can be ascertained using baseband signalling.
Claims25
An apparatus for connecting a plurality of ADNs (add drop nodes) in a ring network or linear network, the apparatus comprising:
- a cross connect node having a plurality of ADN interfaces each for connection to a respective ADN;
- the cross connect node configured to form the ring network or linear network by selectively including or bypassing each ADN interface.
An add drop node comprising:
- a first broadband modem and a second broadband modem;
- a status indicator;
- a first telephone line interface;
- a second telephone line interface in communication with the status indicator and the second broadband modem;
- a POTS interface;
- a filter to isolate the POTS interface from the second broadband modem;
- a switch having a first state and a second state;
- the switch while in the first state connects the first telephone line interface to the POTS interface to enable a POTS signal to pass between the first telephone line interface and the POTS interface without passing through the filter;
- the switch while in the second state connects the first telephone interface to the POTS interface through the filter to enable a POTS signal to pass between the first telephone line interface and the POTS interface, and connects the first telephone interface to the first broadband modem to enable a broadband signal to pass between the first telephone line interface and the first broadband modem;
- the status indicator and the second broadband modem connected to the second telephone line interface.
A method comprising:
- providing broadband service to a plurality of endpoints with a ring network;
- using a cross connect node to control whether any of the endpoints are bypassed from the ring network.
